To all whom z't'mag concern Australia have invented new and useful Tm: j provements' 1n Threshing- Machines, of

which the following 15 a specification.

This invention of an improved combined. harvesting machine has reference to lm-f provements in the construction and arrange ment of theoperative partsof said machines} of the type which cut the heads from standing'crop, and then thresh and separate the grain therefrom, while the machine is 'traveling in the crop, although some of the im? provements are applicable to header or reaper combined harvesters. The main feature of this machine relates tothe means devised to dispense with the grain elevator: usually employed inharvesting niachlnes.

The grain collected in. this machine is de-' "drums from an liver'ed to removable wheat or graindruins or receptacles while the machine is still at work in the field, and when said grain receptacles are filled, they are removed from the 'machine and replaced gby empty ones, and the grain in the'filled drums may then be transferred to bags. j V j The invention or improvements will now be fully described aided-by a-reference tothe accompanying sheets o'f drawings wherea 7 I 1 conveyer' to thegrain drums J located di- Figure 1 is a plan and Fig, 2 an elevation ofthejnear side offa combined harvesting machine, showing the means fordelivering the" grain to grain Archimedean chute in the;

riddle box.

and the grain 'drum,'and I Fig. 4" is' aside-sectional view of-same, and s i Fig. 5 side sectional detail andlliggb part detail plan of the gridof helical heaters.

The broad uptake elevator E- for the cut 7 or stripped heads lies longitudinally about midway of the combs length and is about one third of its width, while the spindle E Be' it known that I, HUGHfVIoToR Mo KAY, a British subject, residing at 811118111116, in the State of Victoria, Commonwealth of carrying the peg drum G has at its one end vator is supported in bearings also carried I enthe' elevatorcasing, the upper endof.
